To a/ZZ wia/ovm,l it may concern,- I

Be it known that I, JAMES M. KLINE, a citizen Iof the United States, residingY atBeaver- Pennsylvania, have invented anew and useful Hydraulic Ram, of which thefollowing is a This invention relates to improvements inhydraulic rams. Y One. object of the invention is to provide a ram in which the escape -valve is -adjustably Weighted, so that a resistance to the closing movement may be altered in accordance with the volume, pressure, or head of the water. "A further object of the invention is to pro-1 vide a ram with an escape-valve opening or port the area of which may be readily adjustedin accordance with the volume of'water. A still further objectof the invention is to provide a ram in' which avolume of impure water, such as the water of a running stream,-

a spring, to a house or other point of consump-4 tion.. l j "Y A stillfurtber objectief the invention is to provide a hydraulic ram with an air-chamber that inay be readily detached should it become valve, and it maybe held in place by means of a small yoke and asingle set-screw.-

A still further object of the invention is to provide a ram in which the entrance and discharge ports are arranged on the same horizontal line, so that the head of -the water-on entering will serve to assist in discharging the water, and all unnecessary Waste of pressure or force will be prevented.` 1

With these and other objects-in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafterdescribed, illus trated in the accompanying drawings, and par ticularly pointed out in the appended claims, it being understoodthat various changes in the form, proportions, size, and minordetails of the structure maybe made withoutdeparting from the spirit or sacrificing any of the advantages of the invention. y

In the accompanying drawings, Figure l is a longitudinal sectional elevation of a hydrau-` f `The water-chamber serai-N0. 169,780. (No model.)

lic ramconstructed in accordance with the invention. Fig. Q'is a detail perspective View of the escape-valve, its port, and carryinglever. Fig. 3 is a similar view of the main check-valvev and its cage. Fig. 4 is a detail section of a portion ofthe air-chamber, showingthe pivot-sockets of the air-dome-elamp-V ing yoke;

Similar numerals of reference are employed to indicate corresponding parts throughout the several iigures of the drawings. s

vThe entrance-chamber l of the ram communicates in the usual manner Vwith ,the airchamber 2, and between these two chambers is a check-valve 3 to prevent the backflow of water. As the main portion of the ram is formed of rough cast metal, which would prevent the direct application of a valve with eX- pensive'` finishing, a separate valve-seat 4 isy formed of a ringof metal'otl a shape corresponding'to the crosssectional contour of the inlet andl provided with ears or lugs 5, having suitable openings for the passage of securingbolts. The valve Aproper is formed of a suitably-shaped pieceof leather and is provided `with a weight-plate 7 that'serves in part to maintain the valve member in Vproper position, A

and said plate is confined in place by a suitable bolt4 8, `extending through the valve and 4through a small metallic plate 9, arranged at the inner face of the valve and entering the inlet when the valve is closed. I

The valve proper may be formed of a piece of leather or other suitable material, and its upper end is somewhat contracted in Width andis bent vover an upper flange 10 at the upper portion of thestationary base of the ram and is confined `in place by a bolt 11, that also extends through the upper end of a plate 12.I

This plate forms a valve-cage and is held in proper spaced relation to the valve `by means of lugs or lingers 13, thatrest Vagainst the inner4 Wall of the"-airchamber, the plate preventing excessive openingmov'ement of the valve. j` Y l is provided with a vertically-disposed flange l 5, defining an opening 16, which may be. of rectangular or other form, and on this ange is seated a cover 17, that may be bolted or otherwise secured to the ears or lugs projecting from the iiange,

and said cover-plate is preferably disposed at' an angle to the horizontal in order that the action of the valve, which at times covers openings in the cover, may he made more uniform and regular. The cover 17 is provided with a number of openings 18 and has a revoluble regulating-disk 19, provided with similar openings 20.

The disk is provided with a pair of-arcuate slots 21, through which pass bolts 22, the construction permitting rotative movement of the disk to an extent sufficient lto secure `the regular adjustment of the openings, and by tightening the bolts the disk may be locked inanydesred position. This featurelis irnportant in .that it permits of the adjustment of the device in accordance with the quantity of Water,l and this prevents the waste of wa-v of Ithe bar extends through a collar 25, formed at the upper end of an arm 26', the lowerl end of saielarm having trunnions 27, adapted to suitable bearings in blocks28, `that are carried by the rearwardly-extended -portion of the cover-plate 17 for conveniencel in manufacture. The hollow bar23 is locked in the sleeve or collar 25 b y means of. a pair of setscrews 2 '9, while the weight isheld in any position to which itmay be adjusted by .means of a set-screw 30, passing through a threaded opening in the sleeveA or collar. and an auxiliary opening. in the hollow bar 23. This weight may be adjusted in order that .greater or less resistance may be offered tothe closing movement of the valve, andl thus-govern the speed of operation of the ram and the pressure imparted to the water, so that the water may bezelevatedto a greater or` less height.

The air-chamberv has a removable; dome31, that'isseated/on the upper flange of the body portion or box of the air-chamber and is held in place by means of a yoke' 32. The lower en ds of the yoke are turned inward and are received in suitable openings in opposite-sides of the body portion of the air-chamber, while the upper orV centralportion of theI yoke has athreaded opening for the reception of a setscrew 33, which bears against the top of the dome and forces the same firmly against its seat, a suitable packing-ring 311 beinggintroduced between the l dorneand flange in order to form an air-tight joint.

The eduction-pipe -35 is 4arranged in a direct horizontal line' witha water-supply-.pipe 3.6, so that the, course of. the water entering the water-chamber and from thence passing to the air-chamber may be in a direct line with the discharge and all of its power utilized, theforce of the iiow being .added to some extent t0 the rea'tionaryforce due to the expansion of air in thedome 31 in order to check the water through the pipe 35. The

casing is provided with an opening 37, through which air is admitted to renew the supply in 'the air-chamber.

In the operation of the ram as thus Jfar described the water entering the chamber 1 ,irst escapes past the valve 22 and then in the pecially where the water is to he used vfor drinking purposes and where the-supply is limited, it is designed to utilize a body of impure-water for pumping purposes. It often happens that a spring or similar source of pure-water supply is adjacent to a running stream the power of, which would be sufficient to force the .spring-water to the point of consumption, while the quantity of water in the spring would not be suicient for the purpose. In such cases the less desirable or impure water may bemade to force the springwater lwithout waste to the point ofconsumption. This is accomplished by tapping into the air-chamber 1.a feed-pipe 40, communicating with the spring, and the water from the spring ows through this pipe to the water-chamber. a constant stream, a check-valve 41 being introduced in the pipein order to.

prevent backilow at any time. The purer water will fill the space from a point intermediateofthe escape-valve and.` the pipe 40 to the eduction-pipe 35, while the impure water entering through the pipe 36 will not mingle therewith, and the force or head of both bodies of water is utilized in pumping the spring-water through the pipe 35.

In the starting of the operation it may be assumed that the two bodies ofv water entering through the` pipes 36 and 40 will both flow in the direction of the escape-valve 22, but owing to the superior volume of impure water a comparative proportion of the springwater will escape, but-the inflow will be suiiicient to prevent the purer water from passing beyond the pipe 4:0. The usual operation will then followat regular intervals, the escapevalve being closed, and the water in the chamber.1 will be moved in the direction of the airchamber 2,' opening the check-valve 3 against the pressure of air in the chamber 2. It is only thespringwaten however, which enters the air-chamber. On the closing of the check-valve 3 and the regurgitation of the water the small body of spring-water left in the water-chamber will tend to force back the impure water, and both bodies of water will, as before, iiow in IOO the direction of the escape-valve. The supplypipes are so proportioned as to prevent intermingling of any of the impure water with the spring-water, and this can only occur where' the volume of spring-wateris less than the pumping capacity of the ram. rI he amount of water utilized may be adjusted by means of the valve 22, and the speed of operation of the ram and the pressure exerted on the water may be readily adjusted by shifting the Vweight 24 in the hollow bar 23.

Having thus described the invent1on,'vvhat is claimed is i l. In a hydraulic ram, an escape-valve, a hollow barcarrying said valve, a pivotallymounted arm having a clamping sleeve or collar for engaging said bar, a slidable weight l for which said hollow kbar forms a housing and in which it is longitudinally adjustable,

and a set-screw carried by the sleeve or collar and extending through an opening 1n the bar to engage and lock the weight in adjusted position.

2. In a hydraulic ram, a water-chamber having an escape-valve opening, a ported coverplate for the openinggran escape-valve adapted to seat against the under side of said plate, a pair of spaced'bearing-boxes carried by the plate, an arm having trunnions adapted to said bearing-boxes, a sleeve or collar carried by the arm, a hollow bar clamped to said sleeve or collar and connected to the valve, a

v against the outer surface of the wall and adjustable thereon to vary the effective area of the escape-ports, both the regulating-disk and thev upper wall having central lopenings for the passage of the escape-valve carrying-rod,

' and means for locking the regulating-.disk in adjusted position.

4. In a hydraulic ram, a water-chamber, a detachable ported cover-plate forming the upper wall of the chamber, said plate being provided with a4 plurality of escape-ports and having an approximately central opening, an

escape-valve adapted to seat against lthe inner face of the plate, a ported regulating-disk for adjusting the elective area of the escapeports, said regulating-disk being arranged on the upper surface of the plate and being provided with a pair of diametrically-opposed arcuate slots and having a centrally-disposed opening alining with the openingof the coverplate, Aguiding and locking bolts extending vthrough the arcuate slotsand tapped into the cover-plate, said bolts forming guides for the movement of the disk-valve, and an escape- Vvalve carrying-bar extending loosely through the central openings of the disk-valve and cover-plate'. v

5. In 'a hydraulic ram, al box or casing divided into a water-chamber and an air-chamber, a ring arranged around the opening between the ltwo chambers and forming a valveseat, a flexible valve adapted to the vseat and connected at its upper end to the wall of the air-chamber, a weight-plate secured to the lower portion of the valve and serving to hold the same in proper position, and an auxiliary j plate having a plurality of studs or fingers and forming a cage for the valve', substantially l as speciiied.
